Further on AT&T Alliance Teleconferencing 700-456-
Mark J. Cuccia
is _NOT_ your primary inTER-LATA carrier, or you have "no-PIC" for
inTER-LATA ...
0-700-456-1000 attempts to route to the "default" conference bridge
that you "home" on. If you "home" on Chicago or Dallas for the AT&T
Alliance Conference Bridge, dialing this 700-456-1000 'default'
number will give you the message about the change in Alliance, as
mentioned in the earlier post on AT&T's 700 SAC-NPA.
0-700-456-1001 seems to still route to the Reno NV bridge (back in
the 1980's, the bridge on -1001 was in southern CA).
0-700-456-1003 seems to still route to the White Plains NY bridge.
0-700-456-1002 (previously the Chicago IL bridge) and 0-700-456-1004
(previously the Dallas TX bridge) presently seem to go to "busy".
If your "default homing" would be on the Reno NV or White Plains NY
bridge, I only _assume_ that 0-700-456-1000 will still go to that
Alliance Conference bridge as previously. But I guess that AT&T will
eventually put the "change" announcements on these bridges soon.
Incidently, dialing an AT&T-handled 500-NXX-xxxx number as a _0+_
call will first get an announcement that the service will be
discontinued, and then give you the opportunity to connect to that
number with a calling-card or a pre-arranged "PIN". However, when
using _1+_, you still through to the number with no "pending
discontinuance" announcement.
As for the AT&T 500-NXX's, if AT&T is _NOT_ your primary inTER-LATA
carrier (and you are also calling from a POTS non-restricted line or
phone), 1+ or 0+ is _NOT_ prececded by a 101-XXXX+ code. The 500-NXX
code is supposed to identify the carrier for the local telco to hand
the call off to.
